Abstract
In the majority of neurosurgical operations, brain refraction is one of the essential techniques. When the stress of retraction becomes too high, because of the occlusion of the blood vessel, saturation of oxygen (SO2) in the retracted tissue would be decreased. Every neurosurgeon knows the safe limits of retraction from one’s experience. However, the clinical technique to measure the oxygenation state of retracted tissue has not been developed yet. We have developed a new optical probe (retractor-type probe) that enables quantitative measurement of SO2 in the retracted tissue. From the experimental use of the retractor-type probe, the feasibility of the SO2 measurement during brain retraction was confirmed. Additionally, the relationship between stress and SO2 in the brain tissue is discussed.
